What do you think about this? (I could also create a small PR for this)

Another important precondition is that all the savepoint data must be
accessible from the new installation under the same (absolute) path. This also
includes access to any additional files that are referenced from inside the
savepoint file (the output from state backend snapshots), including, but not
limited to additional referenced savepoints from modifications with the State
Processor API *link*. Any savepoint data is currently referenced by absolute
paths inside the meta data file and thus a savepoint is typically not
relocatable via typical filesystem operations.

> This section from
> https://ci.apache.org/projects/flink/flink-docs-stable/ops/upgrading.html#preconditions
> states that savepoints are relocatable which they are not yet (see
> FLINK-5763). It should be fixed and/or removed; I'm unsure what change from
> 1.3 it should actually reflect.
> {quote}Another important precondition is that for savepoints taken before
> Flink 1.3.x, all the savepoint data must be accessible from the new
> installation and reside under the same absolute path. Before Flink 1.3.x, the
> savepoint data is typically not self-contained in just the created savepoint
> file. Additional files can be referenced from inside the savepoint file (e.g.
> the output from state backend snapshots). Since Flink 1.3.x, this is no
> longer a limitation; savepoints can be relocated using typical filesystem
> operations..{quote}
